Five letters from Lartizien de Beauvoir addressed to the Chevalier de Beauvain, royal geographer at Paris, dated 1749 to 1775. Bound together with these letters, in a different hand, are Joseph Nicolas de Lisle's "Avertissement aux astonomes sur le passage de Mercure" and "Remarques sur la 'Géographie' de Mr. [Charles] Noblot ou corrections à faire aux six volumes."
